MANUFACTURE OF BISCUITS.

Original applicatiouflled February 8', 1922, Serial No. 534,910, and in Great Brltain February 16, 1991. Divided and thisapplication filed August 4, 1924. Serial No. 730,113.

This invention relates to machines for use in the manufacture of biscuits and the like and more particularly of the general class in which a sheet of dough, paste or similar substance is passed on a conveyor or web over a table beneath a series of combined cutters and-embossers which may serve also as ejectors and isconveyed thence by said conveyor to be delivered to pans or equivalents in which they are delivered to an oven or otherwise dealt with.

Cuttin embossin and ejecting mechaas descri ed forms the subject matter of my concurrent application Serial No, 534,910 .of which the present application is a division the subject matter 0 this present application relating to the means for feeding the cut biscuits ,from the delivery conveyor to the pans, controlling the movements of the latter in relation to said conveyor and in relation to the cutting mechanism.

The essential features of the invention and combinations of parts involved therein are specifically set forth in appended claims and hereinafter fully described with reference to the accompanying drawings certain figuresof which show parts of the cutting mechanism of the ap lication 534,910 aforesaid associated with the features of the present invention.

In said drawings Fig. 1 is a side-elevation of the cutting mechanism with associated epicyclic gearing by which thepan conveyor is driven. ig. 2 is a partial plan of Fig. 1 and partial sectional plan thereof. Fig. 3 is an end elevation of clutch mechanism and associated parts cooperating with the epicyclic gearing. Fig. 4 is a side elevation of the panning mechanism. Fig. 5 is a plan view of Fig. 4 with certain parts omitted, Figs. 6 and 7 are diagrammatic views showing in two positions the conveyor which conveys the cut biscuits to the panning mechanism. Fig. 7 a is a section on an enlarged scale on line 7- a of Fig. 5. Fig. 7 is a detail view on an enlar ed scale showing the right hand endof t e slide 63 and associated parts. Fig. 7 is a plan view. of Fig. 7 with parts in section. Fig. 8 is a side elevation of the epicyclic gearing aforesaidand Fig. 9 is a partial section on the line 9-9 of F1g. 8.

In the said drawings designates the conveyor web which carries the sheet of dough. The cutting device include the cutters' 2, embossers and ejectors 3 and table 4 are mounted in side frame 5' which are given a rocking movement through a wide are about the axis of a shaft 6 at the base of the machine.

Cams 7 and 8 and 44 respectivelyfor operating the rocking frames 5 and embosser cross-head 36 and the "shaft 6 for o crating the cutter cross-head 28 as describe in the concurrent application before referred to are driven throu h a suitable train of spurgear 53, 54, 55, from amain drive-shaft 56 said gear train being further extended by another gear 57 to actuate an epicyclic gearing 57 and through the latter control the pan conveyor as will be described, later.

After passing from under the cutter head, the sheet of dough is conveyed by the web 1 p to the panning portion ofthe machine illustrated in Figs 4 to 7 where the cut and ejected biscuits, after disposal of the scrap in any approved manner, are delivered to the pans, trays or equivalents, which aremoved along on a continuously moving pan conveyor 58 below the delivery end of the web 1 conveying the cut biscuits. The a lateral sleeves 65 (Figs. 4 and 5)- which em brace stationary guide rods 64 at each side of the machine and is reciprocated b means of a toothed segment 93 meshin wit a rack 94 (one at each side) guided in a side frame and connected to a rod 96 which in turn is-attached to a bracket 96 (Fig. 7) by means of a bolt 96*, the bracket in turn the slide by a stud 96 bein connectettlgto whidh extends rough one of the sideflanges of the slide and is secured by a nut 96. The

slide carries at its forward end a knife edge 59 about which passes the Web, the latter then returning and being passed about a roller 62 mounted in a bracket 62 carried by the slide,-and thence about another. roller 62 mounted on a block 62 which is adjustable in a s1ot62-in the side frame memher 62'. From said roller 62 the web m-sses back over a uide roller 62 to the cutting mechanism. he roller 62 is adjustable in the slot 62 by means of a rod 67 and bevel wheels 67, 67 the latter being mounted on a shaft 66 carrying hand wheels 66, 66 (one for single and the other for double ad ustmentzI so that any slack in the web 1 may be ta en up.

The aforesaid bolts 96 carry rollers 62 which run in slotted guides 79 and thus keep the movements of the slide in a rectilinear path.

By the construction above described the delivery end of the web passing about the knife edge 59 is thus caused to advance Figs. 6 and 7) and recede (Fig. 7) whilst t e web remains taut throughout.

.The knife edge 59 is mounted for angular adjustment in relation to the shde 63 by means of a segment 69 and screw 68.

The knife edge 59 is adjustable longitudinally to further take up any slack of the web 1 by assing the bolt 71 through a slot 71 in a ange 59 of the knlfe edge and locking it in required position in saidslot by means of a bolt 70.

The adjusting means described are shown in Fig. 5 as provided at both sides of the machine. g

The operation of the machine at this point is as follows: The knife edge 59 advances at the same speed as the web 1 carrying the biscuits, so that-durin this forward travel of the knife edge, to t 1e right in Fig. 5, no biscuits are delivered from the web to the pans on the conveyor 58 the web being in the position shown in Fig. 6. At the forward end of the stroke of said knife edge the pan conveyor 58 is so adjusted that the front edge of a pan is immediately below the delivery point of the web. The knife edge now commences to recede (to the left in Fig. 5) the pans meanwhile moving forward at the same speed as the web 1 and the result is that the biscuits are peeled from the web onto the pan until it is filled with biscuits, this occurring when the web has reached the position shown in Fig. 7. The knife edgewill then once more advance (to the right) and during this forward travel and while no panning is taking place, the pans on com veyor 58 are caused to move faster than the 'speed of the web 1. In this way the pans will have been skipped forward so that when the next panning or recedingstroke of the knife edge commences, the space between the filled pan and the one following will have been taken "up and the knife edge will be in position over the front edge of the next pan to commence the panning stroke. The pan conveyor passes at the delivery end about sprockets 72 and 73 and thence back to the feed end about a sprocket 74 and is caused to move at the two speeds described above, by being driven through a pair of specially constructed intermeslnng gear wheels 75 and 76 the teeth on each of which i wheel 75 to move faster at one part of the revolution than at the other for the purpose stated. Any other suitable mechanism may be used to produce the same elfcct. During delivery the knife-edge is brought as close to the surface of the pan as possible. It is, however, necessary that said knife edge and parts of the web adjacent thereto should be lifted during the forward (right' hand) stroke of the knife-edge to permit the driving projections 58 of the pan conveyor to pass under the knife edge without contact, and for this purpose the guides 79 are carried by side levers 81 adapted to be rocked about pivots 82 at the proper moment, to lift the knife edge as stated. This is effected by cams 83 mounted on shaft 84 which carries the gear wheel 76 before mentioned and acting on arms 85 secured to the side levers 81 or to their pivots. Springs 81 are provided to maintain the arms in contact with the cams. The shaft 84 on which said cams are mounted may also operate by means of another cam 86, thereon a bar 87 carrying two rollers 88 and 89.

This bar has a toothed portion 90 which meshes with teeth 91 on a segment 92 having also other teeth 93 meshing with a rack 94.011 a slide 95 connected by rod 96 to the carriage 63 carrying the delivery end of the web so that the latter and the carriage are reciprocated as previously explained. The segment 93 and rack and slide 94, 95,

with rod 96 are duplicated on the other side of the machine.

The'drive for the cam shaft-84 is shown as effected by means ofbevel gears 97, 98, and a longitudinal shaft 99 actuated through worm gear 100 from the epicyclic gearing previously referred to (see also Fig. l).

The position at which the biscuits are fed to the pans is the most convenient one for occupation by an operative, since from there said operative may observe whether the panning operation is being properly performed.

It is therefore desirable that. the panningclutch are. so constructed, however,

- of is here deemed necessary.

gard to the ing. 'Thus if the biscuits should overlap shaft 102 operates the clutch by means of the lever and link system, 104, 105, 106, 107 shown in Figs. 1 and 3.

The clutch is interposed in the main shaft 57 of the epicyclic gearing 57 and is under the action of a spring 108. The dogs of the that if not held positively out of gear by the means described they will automatically re-engage under the action of the spring 108 at the next revolution of the driving shaft 57* and allow the pan conveyor 58 to move forward again. By this device the operative may remove defective biscuits from and re-arrange the sound biscuits on the pans so that the latter are completely filled with perfectly formed biscuits. y

The epicyclic gearing above referred to is suitably of the typedisclosed in Patent N 0. 1,109,895 and no detail description there- Ad ustment of said gearing to ensure proper synchronization of movement or time relation between the pan conveyor 58 and associated parts relatively to the cutting, embossing and ejecting elements may however also be performed from the aforesaid control position as by means of a rod 109 extending through the rock shaft 102 previously mentioned and rotated by a hand-wheel 110', this rod extending to they gearing (Figs. 1, 8 and 9) and being connected as by worm gear 111 to adjust the parts thereof by the worm gear moving round the sun wheel 109 of the gear.

to the required adjusted position with replanetwheels 109, of the gearthe end of the web at the panning position, or should be too far back on the web for proper panning, this can be corrected by the means described.

Between the epicyclic gear and the worm gear 100 driving the panning mechanism, there is provided a train gearing the ratio of which can be varied to alter the number of strokes made by the cutter for each pan filled with biscuits, which regulates the numjusted I engages a third change ber of rows of biscuits deposited on the pan.

This train of gearing comprises a pinion 112 driven from theepicyclic gear which engages another pinion 113 carried in a quadrant arm'114 arranged to be manually adaround the centre 112 of the first pinion 112 and the epicyclic gearing as a whole.

The pinion 113carried on the quadrant gear wheel 115, mounted on the shaft 100" of one'element of theworm gear 100 the size of said wheel 115 depending on the number of rows of biscuits required on the pan. The adjustablequadrant 11; is held in position for the gears to mesh correctly for each speed by a locatmoving. feed web for gages some fixed frame part, for example the frame 117 (Fig. 1) at the rear of thequadrant.
